Doug Skorupski of Volkswagon, with a list of clean diesel models, says about 50 percent of filling stations have a diesel pump.

“When you ask somebody who doesn’t own a diesel engine, are they concerned about the availability of diesel if they were to purchase a diesel vehicle, they definitely would say yes. When you ask that same question to somebody that owns a diesel vehicle, is there any issue filling up, finding diesel fuel stations and the answer is no.”

Diesel vehicles and fuel cost more but Skorupski says a little number crunching shows a driver may be ahead of the game after three or four years, depending on fuel economy and driving habits.

Clean diesel is the result of now-required Ultra Low Sulfur Diesel fuel.
